Abstract
The present invention provides for an indicia bearing elastomeric article with a smooth outer surface and a process for making the article. The indicia bearing elastomeric article includes a polymer film having indicia on one of its surfaces bonded to and flush with an elastomer layer. Since the outer surface of the article is without surface irregularities caused by the known transfer release techniques, power transmissions belts employing the invention do not generate the unwanted noise caused by the irregular surface contacting pulleys and idler rolls. The indicia provided by the invention can provide durable labeling for the article which remains visible throughout the useful life of the article.
Claims6
An indicia bearing elastomeric article having an outer surface, said article comprising:
- an elastomer layer having an outer and inner surface;
- a polymer film having an outer and inner surface, said film having indicia on one of said surfaces, said film being a fluoropolymer film comprising a fluoropolymer selected from the group consisting of polymers and copolymers of trifluoroethylene, hexafluoropropylene, monochlorotrifluoroethylene, dichlorodifluoroethylene, tetrafluoroethylene, vinylidene fluoride and vinyl fluoride;
- wherein said inner surface of said polymer film is bonded to said outer surface of said elastomer layer and said outer surface of said polymer film is flush with said outer surface of said elastomer layer making smooth said outer surface of said elastomeric article.
